Confidential, FMCA only.
Work Items refer only to Technical Issues & Opportunities not (previously) identified by one of the FMCA Technical Working Groups, whilst scoping out requirements for a new PRD.
Work Items may relate, for example, to a request to add an entirely new PRD
Section to a PRD which is under development (Draft Status), or to a new opportunity to bring a FMCA Technical Contribution to a Standards Development,
Specifications or Certifications Organisation.
Any proposal for additional technical work within FMCA – as per above guidelines – must be submitted to the FMCA Priority Programme #02 Lead and
Technical Lead for consideration, using this Work Items Template.
Once completed, this document must be submitted via the FMCA
Document Management System’s (DMS) group email: ap_devices_wg@thefmcadms.com
Please submit only one Work Item Proposal per template.

Proposed contribution to Standards/Industry Alliances 

Submission date: 24 th April 2008
Work Item Title (to be used whenever referencing this document):
Media Independent handover (802.21)
PRD to which contributions applies (optional):
Rationale:
The FMCA is seen as a suitable framework to combine the efforts of those working on
MIH and test how its components can interoperate across vendor’s and operator’s implementations. A Profile document will provide a recommended subset of the standard for industry. User trials will help to determine the possibilities for commercial deployment.

802.21 – Media Independent handover is an emerging standard in heterogeneous handover. See accompanying documents for details. BT, Intel, and more recently Nokia and NSN, have been working on a successful collaboration for the last 2 years implementing the latest version of the standard to understand its capabilities and determine its possible benefits for operators and vendors.
The first implementation was demonstrated at the Intel Developer’s Forum (IDF) in San
Francisco in September 2006 and showed handover between WLAN and WiMAX. Most recently the demonstrator has been shown at the Mobile World Congress (MWC, formerly the
3GSM) in Barcelona, February 2008. The latest demonstration also showed WLAN to WiMAX handover, this time with a fully implemented Information Server. We are also able to demonstrate seamless handovers between 3G and LAN.
As our work has developed there has been more and more interest in further collaboration from other operators and vendors. The obvious way forward for the work would be to define an agreed subset or profile for the 802.21 standard and test this profile in an interoperability event.
The ultimate goal would be a user trial to measure the performance of 802.21 in a realistic environment and determine its possibilities for commercial deployment.
We see the FMCA as a suitable framework to take this work forward.
++++++++++++++++++++++
Proposed work items (input from BT and KT):


User and handover scenarios e.g. o Device initiated handover o Network initiated handover

MIH framework – define agreed subset or profile

MIH terminal platform o Developing common API set for operators and application developers o Defining low-level device interface o Or common use or development of MIH core software

